RC4 is now disabled by default in OpenJDK 6 and OpenJDK 7
Earlier _OpenJDK_ packages allowed the RC4 cryptographic algorithm to be used when making secure connections using Transport Layer Security (TLS). This algorithm is no longer secure, and it has been disabled in this release. To retain its use, it is necessary to revert to the earlier setting of the `jdk.tls.disabledAlgorithms` of `SSLv3, DH keySize < 768`. This can be done permanently in the `<java.home>/jre/lib/security/java.security` file or by adding the following line:
jdk.tls.disabledAlgorithms=SSLv3, DH keySize < 768
to a new text file and passing the location of that file to Java on the command line using the `-Djava.security.properties=<path to file>` argument.
